ABSTRACT: Background
The type of major duodenal papilla could be associated with difficult biliary cannulation at first endoscopic retrograde cholangiopancreatography (ERCP) in adults. Methods

The outcome of interest was difficult biliary cannulation, defined according to the European Society of Gastroenterology. To assess the association of interest, we calculated crude and adjusted prevalence ratios (PRc and PRa, respectively) and their respective 95% confidence intervals (CI) using Poisson regression with robust variance models, employing bootstrap methods.
